氧化态CoFeB中的MegaOhm异常霍尔效应
MegaOhm Extraordinary Hall effect in oxidized CoFeB
摘要：
我们报道了可控氧化CoFeB铁磁薄膜的发展，该薄膜具有超过1欧姆cm的非凡霍尔效应（EHE）电阻率和高达10^6欧姆/T的磁场灵敏度。这种EHE电阻率比以前在铁磁材料中观察到的高四个数量级，而灵敏度比最好的半导体大两个数量级
英文摘要：
We report on development of controllably oxidized CoFeB ferromagnetic films demonstrating the extraordinary Hall effect (EHE) resistivity exceeding 1 Ohmcm and magnetic field sensitivity up to 10^6 Ohm/T. Such EHE resistivity is four orders of magnitude higher than previously observed in ferromagnetic materials, while sensitivity is two orders larger than the best of semiconductors
